Appl'ieati med 'october 9,'

' vention being herein explained and the best mode in which I have contemplated applying that principle, so as 'to distinguish' 1t from other inventions.

lMy invention relates to traverse mechanism for winding machines and particularly to apparatus of this -character utilized for winding upon bobbins artiflcialsilk such as viscose threads. Particularly, my-invention -relates to means-in apparatus of this `character in' which thezthread is subjected to a minimum amount of friction when being wound.v 'v The annexed drawings and the following descri tion set forth in detail certain means embo ying my invention, the' disclosed means, however, constituting but one of the various mechanical forms in which the prinl ci le of, the invention may be employed.

Referring t'o the annex d drawings, a plu? y rality of pairs of vshafts 1 and 2f are mounted in a suitable frame, veachpair of shafts, in the 'manner hereinafter f fullygdescribed,

forming part of the means for rotating by frictional rolling'contact a series of longl- '.tudinall disposed bobbins 25. To each of the shas land 2 and `adjacently one end thereof is secured a pinion 3, an idler 4 being positioned between the vtwo pinions of the Specification of Letters Patent.'

said .surfaces,'as plainly shown in Figure 1.

The bobbins -when' filledl are thus easlly rel vmoved and replaced. The body' of thread 26,' shown -in Figmres '1-'and 4, represents the 'condition 'when' a bobbin 2 5 isl wound' .ond 'gui e 29 positioned in and extending from .a trough 60 containing the usual pra' pressed vab'outhalf full .of the viscose thread 27 re- "ceived b a porcelain guide 28 from a seccontained in the vtrough -60 where it 'is pre-'fi cipitated and solidified intofthe thread' 27.

the 32 is 'securedto a handle56 pivotedf loof, `'In-order that-thethread may be wound l upon the bar '31. Also secured said hub" fully described.- Mounted intermediate of portion .is a downwardly extending arm A36 formed with brackets 37. supporting an externally threaded member38. Afcasting 39 may be reciprocated vertically upon the screw 38 bl the means hereinafter fully def scribed. ecured to this.. casting 39 is a link whose other end ispivotally connected to one endofa transversely extend'- ing arm 40', Figure l, which is pvoted at its other end to the frame of the machine, part'of the means forming said pivotal 'connection between the link 40 and the arm 40 consisting of a rounded end portion 402 upon the arm 40 by means of .which the arm" 40" may/be moved longitudinally of the outer endV of the'link 40, fora purpose hereinafter the ends of the arm 40 is a anged roller 42 adapted to ride upon a face cam 43 secured to the power shaft 20, said roller being held'to .position bya spring 44, Figure 4. It is evidentthat the apparatus ls o far de` scribed will rovide'means for rotating the` bobbins 25 Ay frictional contact and vf or winding the thread 27 4longitudinally of said lso bobbins. The arrangement is.y such, as

plainly shownrin Figures 1 and 4, that a very small number of rotations ofthe shafts 1 and 2 t'alires lace'duri'ng a single reciprocation ofthe Ear 31, so that theA thread 27 is wound upoIr the bobbin 25 with comparatively large open .spaces between adjacent. turns ofthe thread. A 1

. As is plainly apparent in Figures 1 and 4,

the thread 27 yis so wound upon the bobbinv w25 as to provide at each end of the body 26 of thread a beveled edge 26';l .This is to insure the inte ity 'ofthe wound. thread against unravelrng and 'is attained "by the" following. means. l

Secured to the bottom of the screwN inem'-A tion of the link 4 0 this ratchet" 45 is adapted 'to strike a vrigidstop 46 so as to slightly turn the ratchet 45.` lReferring to Figure 6, it will be noted that the vertically-movable casting 39' is intersected by a pair ofblocks :47. VThese .blocks are the only. members'that '.38 and are heldv to such. threaded vengagehave lthreaded engagement withrthe screw ment byv a spring 48, Figure-'7. The result is that the casting-or crosshead. 39 is fed downwardly slightly each time thefratchet 55 45 strikes the stop. 46 to shorten up the'v stroke of the bar 31 upon vwhich the por` celain guides 28 are mounted. Whenever it is desired to returnthe crosshead 39 to the top ',of the screw member 38 to start a new stroke, after one bobbin 25 has been fully wound, the spring 48 is loosened manuallyb. to release the blocks 47 from the screw Inember 38 and the crosshead 39 shoved up to the proper position by means of a handle 49.

lt. is evident that, d ue to the' increasing part of the invention duced portion 73 of the shaft 7.,

. lt will be noted in Figure` 1 that adjacent longitudinal pairs. of the ro1lers'23 and 24v are not utilized at the same time but that the bobbins 25l are mounted on alternate 1' pairs. The result is that when the Vbobbin dianieter `of the body. of thread 26, more thread 27 willv` be wound upon the bobbin 'at each turn of the bobbin. In order to 1 and 2. Generally, this is accomplished by a change in the position of thefriction disc 8 upon the-friction disc 16 at each turn of .the shaftl 20. The detail of this arrange ment consists of the .following means which, however, as stated above, do not form any claimed in 'this application. l. v- Loosely mounted upon a sleeve 10 -rotatablymounted upon theshaft 7 is a bell crank having arms 1l and 11. Secured to the arm v llbya suitable .pin is a pawl 13. This pawl .cooperates with the' ratchet 14 fixed by any' suitable means to the sleeve 10 -andflXed-longitudinally of the shaft 7 by means of a' shoulder 9'of the friction disc 8 member l() is formed with a peripheral screw .threaded portion adapted to cooperate with These blocks 51 are held to engagement with the sleeve 10 by means of a spring 52,` F igure 3. The other arm 11 ofthe bellcrank v"is secured to the top of a vertically disposed .eccentric rod 53which'in' turn/isfsecured at its lower end to .y an eccentric strap 54 securedto the driving shaft 20. .It is evident that each rotation o fzthedriving shaft 20 will result in ja 7 feeding oflthe sleeve 10- throughthe nut and consequently in'a' movement' of the friction disc 8 toward the` center ofthe friction discl, thus slowing up the speed of -rotationbfthe shaft 7 and.

consequently of .the :roller shafts 1 and2. In order that the :highest rate of speed of the shafts land 2 may be secured atthe time .of thewindingupon a new bobbin,'the sleeve l. 10.is relieved from'theblocks `51 bymeans Vofreleasing manually thespring 52, and the l frictiondisc -8 and shaft 7 .pushed to the right, Figurei 2, by means of a' handle 55,

being secured by a running fit in a suitable groove. formed in the sleeve. 10. rlhis sleeve f loo the locklng pin- 55 lslidingbin the annular recess 7 2 formed aroundan intermediate remounted upon one pair vof said rollers is A yhandlef56, Figure 4,'is pivoted to the lfull wound, the bar 31 is shifted longitudivthe said bar 31 then manually shoved longitudinally until the pin 57 lies in the former position of the pin 562 when, by lowering the handle and locking the pin 562 in the position 56', the pin 32 again registers with the yoke 33 andthe guides 28 are disposed adjacently the alternate bobbins 25.

It will be evident from the accompanying drawings that only one unit of my improved winding machinehas been described and that the entire -machine consists of a multiplicity of said units, two or more pairs of shafts 1 and 2 being operated simultaneously by means of multiple arms 34 and 34', multiple pinions 3 and other necessary multiple parts.
